Let's skip right past the cringe-worthy "Declaration of Energy Independence" slogan and look at what the Eagles are actually doing with their pro sports venue. The franchise that dresses in midnight green is aiming to smarten up its eco-green credentials with a new partnership with SolarBlue that will provide all of the Eagles' stadium energy needs for the next 20 years, after which point the team will be free to resell any surplus electricity back to the grid. 15 percent of the total output with be generated with spiral wind turbines erected around the top rim of Lincoln Financial Field, another 15 will come from 2,500 solar panels to be installed near the stadium, and the rest will be obtained from a biodiesel / natural gas plant. So it's not all renewable, but a nice step in the right direction, nonetheless.
